When a Samsung dishwasher suddenly shows an error code, it’s the machine’s way of signaling a problem. These codes may look confusing at first, but each one points to a specific fault. Understanding the most common codes can save time and help you know whether a quick adjustment will solve the issue or if professional repair is required.

LC – Leak Detected

This code appears when the sensor identifies water where it should not be.
How to respond: Disconnect power, inspect the base of the dishwasher for moisture, and make sure the detergent being used is appropriate. If the message stays even with no visible leaks, the sensor or water lines may need service.

4C – Water Supply Problem

The dishwasher is not receiving enough water.
How to respond: Confirm the supply valve is open, check the inlet hose for blockages, and clean the filter. If the water flow is fine and the error returns, the inlet valve itself may be defective.

5C (SC) – Drainage Error

This code means the appliance cannot empty water.
How to respond: Clean the drain filter, ensure the hose is free of bends or clogs, and restart the cycle. If water still won’t drain, the pump or internal valve may need replacement.

LE – Low Water Level

The machine senses that the water level is below normal.
How to respond: Restart the dishwasher, check the household water pressure, and clean the filters. If the issue persists, it may point to a faulty sensor or filling system.

HE – Heating Error

The dishwasher has detected a problem with the heater or temperature sensor.
How to respond: Reset power and run a short cycle to see if the error clears. If it continues, the heating element or thermistor likely requires replacement.

Conclusion

Samsung error codes are designed to help identify problems quickly. Some issues, like a clogged filter or kinked hose, can be fixed at home with simple checks. Others, such as heater or sensor failures, usually require professional repair. Knowing the meaning behind the codes helps you react correctly and avoid unnecessary downtime.
